A vertical datum is a reference surface for vertical positions, such as the elevations of Earth features including terrain, bathymetry, water level, and human-made structures. An approximate definition of sea level is the datum WGS 84 , an ellipsoid , whereas a more accurate definition is Earth Gravitational Model 2008 (EGM2008), using at least ...
Edmund Gustav Albrecht Husserl (/ ˈ h ʊ s ɜːr l / HUUSS-url, [14] [15] [16] US also / ˈ h ʊ s ər əl / HUUSS-ər-əl, [17] German: [ˈɛtmʊnt ˈhʊsɐl]; [18] 8 April 1859 – 27 April 1938 [19]) was an Austrian-German philosopher and mathematician who established the school of phenomenology.
Instead of dots some manuscripts exhibit strokes, vertical or else horizontal. The first two explanations are unacceptable for the reason that such faulty readings would belong to Qere and Ketiv, which, in case of doubt, the majority of manuscripts would decide. The last two theories have equal probability. [24]
Page orientation is the way in which a rectangular page is oriented for normal viewing. The two most common types of orientation are portrait and landscape. [ 1] The term "portrait orientation" comes from visual art terminology and describes the dimensions used to capture a person's face and upper body in a picture; in such images, the height ...
The vertical–horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. [1] This involves a bisecting component that causes the bisecting line to appear longer than the line that is bisected. People often overestimate or underestimate the length of the ...
In the three-dimensional case, the situation is more complicated as now one has horizontal and vertical planes in addition to horizontal and vertical lines. Consider a point P and designate a direction through P as vertical. A plane which contains P and is normal to the designated direction is the horizontal plane at P.
In geodesy, surveying, hydrography and navigation, vertical datum or altimetric datum is a reference coordinate surface used for vertical positions, such as the elevations of Earth-bound features ( terrain, bathymetry, water level, and built structures) and altitudes of satellite orbits and in aviation . In planetary science, vertical datums ...
The vertical exaggeration is given by: = where VS is the vertical scale and HS is the horizontal scale, both given as representative fractions.. For example, if 1 centimetre (0.39 in) vertically represents 200 metres (660 ft) and 1 centimetre (0.39 in) horizontally represents 4,000 metres (13,000 ft), the vertical exaggeration, 20×, is given by:
